During the last century the chemical composition of the global atmosphere has changed. These changes will continue in the future with exacerbated speed. Burning of fossil fuels releases gases to the atmosphere that influence plant photosynthesis and growth. One of these gases is carbon dioxide (CO{sub 2}) which is essential for photosynthesis. Higher future levels of CO{sub 2} in the atmosphere are expected to increase plant photosynthetic rates and crop growth. On the other hand, gases such as SO{sub 2}, NO{sub x}, and tropospheric oxidants produced as a direct or indirect result of burning of fossil fuels are known to adversely affect plant leaves, photosynthetic rates, and growth. 62 refs.
